If someone is sitting in a typical living room?
Would you care to elaborate, please and thank you!

Where would the highest concentration of electrons be located?

mathman is right. Neutrons mess the proportions up a bit, but generally, the more mass, the more electrons.
If you're wearing a gold-plated ring, that plating has a good chance of being where the electron density is highest in your room.
There is another interpretation of your question. That would be, where is the highest density of extra electrons in your living room - electrons beyond what are needed to make atoms neutral in charge? Pools of electrons in this sense would be static electrical negative charges - and the "density" would correspond closely to the voltage.
If the humidity is pretty low, you can generate a static charge in the tens of thousands of volts. As the humidity increases, open air static charges drain quickly. Electronics include capacitive charges and a decade ago there was a clear winner in this category. That was when TVs were based on cathode ray tubes and the circuitry included capacitors with whopping charges.
Now, you're probably best looking in the power supplies of you TV, computer, or microwave (although who has a microwave in their living room).

So a giant gold plated Lion-statue would be very high in Electrons?

Recent posts confirm that 'typical' is a subjective term among PF members, who exhibit a variety of taste in their choices of living room decor. 
I was thinking that any type of active waterfall decoration would be an active source of extra electrons/ions. But then I saw this guy's living room...

Uh, this sounds like a trick question...
Concentration, whether mass concentration, molar concentration, number concentration, or volume concentration, is going to be confounded by the electron not having unmeasured mass, amount, number, or volume (volume even when measured), and if you are asking because you don't know, that suggests you have not measured yet... :)
Even if and when you do measure, all these concentrations are based on an arbitrary volume in the denominator, and your choice of location and magnitude of that volume is going to vary your resulting calculation of concentration... in principle you may choose such that the result approaches any value between 0 and 1.
